At least I have. I have handled hundreds of kilos crystall canola honey during decades.
I have not destroyed and melted combs as many on forum advices.
There are several ways. The main problem in Canola is that bees drop the sugar crystalls onto floor and carry them out as rubbish.
Bees clean the combs but you may miss the most of honey. 25% goes to energy when bees move stuff to another place and store it.
1) Give 3 frames to the hive. Scab the cappings off. Spray water on combs.
during 24 hours bees suck part of honey off, perhaps 2 millimetre. Now you may pour water a 2 millimetre layer on crystalls. It goes deeper into honey and after that bees are able to dilute the crystalls.
If you give that during flow, bees cap again the honey. So wait for rainy days or something like that.
2) Put a honey frame between brood frames.
Crab a piece of cappings off , 2-3 inches and spray water. Put that frame between larva frames. Bees start to clean cells for brooding and every week you may give 3 crystallized frames to the hive.
the cleaning capacity of the hive is limited. Don't give too much.
3) Cleaning with swarms.
When you have swarm of artificial swarm, put into box 3 frames crystallized Honey and the rest foundations.
After a week crystall frames are full of brood and foundations have bee drawn.
4) In large scale
Uncap the combs with pressure washer. You whip the capping off. Cells get water too. Then put the uncapped box topmost to the hive.
Next day you see what bees have done.
Pour water over the cells a good layer and put the comb back. If you are lucky, bees lick the honey off and move it deeper into the hive.
This year's late summer I handled about 500 kg crystallized honey but it was not canola.
I got an big accident last summer when wax moth concured my honey comb store. I was afraid to extract honey because wing powder was every where.
This summer I fed the Honey to new honey and it happened more than well.
